Matrx PS Heavy-Duty Cushion

The Invacare Matrx PS Heavy-Duty Cushion is a lightweight, contoured foam wheelchair cushion designed to provide positioning, stability, and everyday sitting comfort for users requiring larger seat dimensions and higher weight capacity. Built with durable high-resilience foam, the PS Heavy-Duty features an anatomically molded shape with a waffled ischial relief recess to help improve immersion, maintain pelvic position, and reduce sliding during daily wheelchair use.

Designed for bariatric seating needs, the Matrx PS Heavy-Duty Cushion supports users up to 600 lbs. and is available in larger sizes than the standard Invacare Matrx PS Cushion. Its moisture-resistant cover system, durable foam construction, and low-maintenance design make it a practical option for manual and power wheelchair users who need dependable positioning support in a heavy-duty configuration.

Heavy-Duty Positioning, Stability & Comfort

The Matrx PS Heavy-Duty Cushion is designed for users who need a larger, higher-capacity cushion without the maintenance requirements of air, gel, or fluid systems. Its contoured foam base helps support pelvic alignment, while the waffled ischial relief area allows improved immersion where seated pressure is often highest.

This combination of contouring, pressure relief, and durable foam support makes the PS Heavy-Duty a strong option for bariatric users, active users, and care environments where a dependable, easy-to-maintain cushion is important.

Cover Design

The Matrx PS Heavy-Duty Cushion is available with cover options designed for different care environments. Breathable fabric cover options support comfort and airflow during everyday use, while wipeable infection-control cover options allow easier cleaning in clinical or facility settings.

Hook-and-loop fastener strips help keep the cushion positioned securely on the wheelchair seat, reducing unwanted movement during daily use. A moisture-resistant inner liner helps protect the foam core and supports easier maintenance.
